Hi,
this question is not directly related to the Eclipse IDE. I've got to
mantain a Java tool that uses JDT to compile some sources, both 1.4 and
1.5, and should be run using a Java 5 runtime.
I have some issues when compiling 1.4 sources (targetting 1.4 platform): I
set the properties org.eclipse.jdt.core.compiler.compliance,
org.eclipse.jdt.core.compiler.source and
org.eclipse.jdt.core.compiler.codegen.targetPlatform to 1.4 so I was able
to compile the code, but now I have a runtime error (invalid BigDecimal
constructor). I suspect this is because JDT compiles against the Java 5
runtime libraries.
Is there any property I can set to force JDT to compile against another
runtime? A sort of "bootclasspath" that I should use with javac.
Thank you.
Regards,
Andrea Bianchi

In addition to setting the compiler compliance, you should also be
setting the JRE Lib to a 1.4 JRE/JDK. that is easy to do in the IDE
(Project Properties > Java Build Path > Libraries tab), but I'm not sure
how you are setting those kinds of things non-interactively.
Hope this helps,
Eric

Thank you for your answers... in the meanwhile I decided to rewrite that
module of the application avoiding jdt to compile classes.
Thank you again,
Andrea
